Solution Overview

Problem

Achieving optimal crop distribution and compression in flat silos for efficient fermentation requires specialized knowledge and manual effort, which can lead to suboptimal results due to variability in crop properties and silo conditions.

Innovation Solution

A method that uses a control unit to determine optimal layer thickness based on crop properties and silo vehicle specifications, automatically adjusting the distribution tool to ensure consistent and optimized layer thickness across the silo, reducing operator workload and improving fermentation outcomes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual distribution and compression methods are used, then operator flexibility and adaptability are maintained, but fermentation results become suboptimal due to variability in crop properties and high demand on operator expertise

Engineering Contradiction:
Improvefermentation resultVSAvoidoperator expertise requirement
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system automatically determines optimal layer thickness and controls the distribution tool based on measured crop properties and silo conditions, enabling the system to self-regulate without requiring operator expertise. The control unit processes sensor data and autonomously adjusts distribution parameters to achieve consistent fermentation results

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical distribution and compression operations are replaced by an automated control system that uses sensors to measure crop properties (moisture content, density) and automatically adjusts layer thickness and distribution parameters, substituting human judgment with instrumental measurement and automated control

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If automated control systems are implemented to optimize layer thickness, then fermentation results improve through consistent distribution, but device complexity increases

Engineering Contradiction:
Improvefermentation resultVSAvoidcontrol system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system incorporates sensors that continuously measure crop properties (moisture content, density) and layer thickness, feeding this information back to the control unit which automatically adjusts distribution parameters. This closed-loop feedback system ensures consistent fermentation results while automating the control process

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The control system dynamically adjusts distribution parameters (layer thickness, distribution width, compaction force) based on measured crop properties and silo conditions, optimizing fermentation outcomes by adapting parameters to actual material characteristics rather than using fixed settings

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If location-specific optimized layer thickness is determined and applied, then manufacturing precision of crop distribution is improved, but the complexity of real-time adjustment increases

Engineering Contradiction:
Improvelayer thickness consistencyVSAvoidreal-time adjustment mechanism
Core Design Contradiction:

Solution Approach 1:

The silo is divided into multiple locations or zones, and the control system determines optimal layer thickness for each specific location based on local conditions (crop properties, silo geometry, compaction requirements). This segmentation allows precise control of layer thickness in different areas while using a unified automated control approach

Inventive Principle:
Principle #1Segmentation
